The use of active crossovers is increasing. They are used by almost every sound reinforcement system, and by almost every recording studio monitoring set-up. There is also a big usage of active crossovers in car audio, with the emphasis on routing the bass to enormous low-frequency loudspeakers. Active crossovers are used to a small but rapidly growing extent in domestic hifi, and I argue that their widespread introduction may be the next big step in this field. The Design of Active Crossovers has now been updated and extended for the Second Edition, taking in developments in loudspeaker technology and crossover design. Many more pre-designed filters are included so that crossover development can be faster and more certain, and the result will have a high performance. The Second Edition continues the tradition of the first in avoiding complicated algebra and complex numbers, with the mathematics reduced to the bare minimum; there is nothing more complicated to grapple with than a square root. New features of the Second Edition include: ? More on loudspeaker configurations and their crossover requirements: MTM Mid-Tweeter-Mid configurations (The d'Appolito arrangement) Line arrays (J arrays) for sound reinforcement Frequency tapering Band zoning Power tapering Constant-Beamwidth Transducer (CBT) loudspeaker arrays ? More on specific sound-reinforcement issues like the loss of high frequencies due to the absorption of sound in air and how it varies. ? Lowpass filters now have their own separate chapter. Much more on third, fourth, fifth, and sixth-order lowpass filters. Many more examples are given with component values ready-calculated ? Highpass filters now have their own separate chapter, complementary to the chapter on lowpass filters. Much more on third, fourth, fifth, and sixth-order highpass filters. Many more examples are given with component values ready-calculated ? A new chapter dealing with filters other than the famous Sallen & Key type. New filter types are introduced such as the third-order multiple feedback filter. There is new information on controlling the Q and gain of state-variable filters. ? More on the performance of crossover filters, covering noise, distortion, and the internal overload problems of filters. ? The chapter on bandpass and notch filters is much extended, with in-depth coverage of the Bainter filter, which can produce beautifully deep notches without precision components or adjustment. ? Much more information on the best ways to combine standard components to get very accurate non-standard values. Not only can you get a very accurate nominal value, but also the effective tolerance of the combination can be significantly better than that of the individual components used. There is no need to keep huge numbers of resistor and capacitor values in stock. ? More on low-noise high-performance balanced line inputs for active crossovers, including versions that give extraordinarily high common-mode rejection. (noise rejection) ? Two new appendices giving extensive lists of crossover patents, and crossover-based articles in journals. This book is packed full of valuable information, with virtually every page revealing nuggets of specialized knowledge never before published. Essential points of theory bearing on practical performance are lucidly and thoroughly explained, with the mathematics kept to an essential minimum. Douglas' background in design for manufacture ensures he keeps a very close eye on the cost of things.

Electronics for Vinyl is the most comprehensive book ever produced on the electronic circuitry needed to extract the best possible signal from grooves in vinyl. What is called the "vinyl revival" is in full swing, and a clear and comprehensive account of the electronics you need is very timely. Vinyl reproduction presents some unique technical challenges; the signal levels from moving-magnet cartridges are low, and those from moving-coil cartridges lower still, so a good deal of high-quality low-noise amplification is required. Some of the features of Electronics for Vinyl include: ? integrating phono amplifiers into a complete preamplifier; ? differing phono amplifier technologies; covering active, passive, and semi-passive RIAA equalisation and transconductance RIAA stages; ? the tricky business of getting really accurate RIAA equalisation without spending a fortune on expensive components, such as switched-gain MM/MC RIAA amplifiers that retain great accuracy at all gains, the effects of finite open-loop gain, cartridge-preamplifier interaction, and so on; ? noise and distortion in phono amplifiers, covering BJTs, FETs, and opamps as input devices, hybrid phono amplifiers, noise in balanced MM inputs, noise weighting, and cartridge load synthesis for ultimately low noise; ? archival and non-standard equalisation for 78s etc.; ? building phono amplifiers with discrete transistors; ? subsonic filtering, covering all-pole filters, elliptical filters, and suppression of subsonics by low-frequency crossfeed, including the unique Devinyliser concept; ? ultrasonic and scratch filtering, including a variety of variable-slope scratch filters; ? line output technology, including zero-impedance outputs, on level indication for optimal setup, and on specialised power supplies; and ? description of six practical projects which range from the simple to the highly sophisticated, but all give exceptional performance. Electronics for Vinyl brings the welcome news that there is simply no need to spend huge sums of money to get performance that is within a hair’s breadth of the best theoretically obtainable. But you do need some specialised knowledge, and here it is.

Audio Electronics provides information pertinent to the fundamental aspects of audio electronics. This book discusses the parallel development in the various transducers and interface devices used to generate and reproduce electrical signals. Organized into nine chapters, this book begins with an overview of the basic method of digitally encoding an analog signal that entails repetitively sampling the input signal at sufficiently brief intervals. This text then examines the major attraction of the FM broadcasting system to allow the transmission of a high quality stereo signal without significant degradation of audio quality. Other chapters consider the conventional practice to interpose a versatile pre-amplifier unit between the power amplifier and the external signal sources. This book discusses as well the requirements for voltage gain stages in both audio amplifiers and integrated-circuit operational amplifiers. The final chapter deals with the significance of the power supply unit. This book is a valuable resource for professional recording and audio engineers.

The groundbreaking Audio Culture: Readings in Modern Music (Continuum; September 2004; paperback original) maps the aural and discursive terrain of vanguard music today. Rather than offering a history of contemporary music, Audio Culture traces the genealogy of current musical practices and theoretical concerns, drawing lines of connection between recent musical production and earlier moments of sonic experimentation. It aims to foreground the various rewirings of musical composition and performance that have taken place in the past few decades and to provide a critical and theoretical language for this new audio culture. This new and expanded edition of the Audio Culture contains twenty-five additional essays, including four newly-commissioned pieces. Taken as a whole, the book explores the interconnections among such forms as minimalism, indeterminacy, musique concrète, free improvisation, experimental music, avant-rock, dub reggae, ambient music, hip hop, and techno via writings by philosophers, cultural theorists, and composers. Instead of focusing on some "crossover" between "high art" and "popular culture," Audio Culture takes all these musics as experimental practices on par with, and linked to, one another. While cultural studies has tended to look at music (primarily popular music) from a sociological perspective, the concern here is philosophical, musical, and historical. Audio Culture includes writing by some of the most important musical thinkers of the past half-century, among them John Cage, Brian Eno, Ornette Coleman, Pauline Oliveros, Maryanne Amacher, Glenn Gould, Umberto Eco, Jacques Attali, Simon Reynolds, Eliane Radigue, David Toop, John Zorn, Karlheinz Stockhausen, and many others. Each essay has its own short introduction, helping the reader to place the essay within musical, historical, and conceptual contexts, and the volume concludes with a glossary, a timeline, and an extensive discography.
